To all whom it may concern: IBe it known that I, ALBERT H. Erinnert,

a citizen of the United States,vres1d1ng at St. Jose h, in the county of Buchanan and 5 Sta-te ci Missouri, have invented certain new and useful Improvements 1n Refrigerator" Display-Counters, of which the followin is a specification.

- gl'hjis invention relates to refrigerators and counters,V and has for its object the improvement of the circulating and cooling eects of the cooling medium. Other objects will become a parent as the invention is more fully set erth.

In the usual type ofA refrigerator counter and ice box, a certain amount of cold air circulation takes4 place, but such is only possible as far as theI natural conditions permitand may be said to be of a spasmodic nature. In thls invention the circulation isl created positivelyr by means of an arrangement whereby the cold lair and warm 4air 1n the refrigerator are directed definitely to where a greater circulation will be created and `all natural drafts reinforced. 'In order to bring about-this action the sides or ends are suitably curved and barriers and other means provided according to afpredete'rmined arrangement conforming to principles under which cold and warm air act when in adjacent relation to one another. e In the accompanying drawings forming a part of this specification, Figure 1 is a vertl- 85: cal longitudinal view artly i1n section showin an embodiment o "this lnvention. 2 1s a transverse section of Fig. 1, throug the central 'portion of the food compartment.

ice supported on anfo n rack or shelf 45.

,i The partitions 6 whic separate the comartments have their upper and lower edges gslanting downwardly toward the ice chamber and upwardly toward Athe 4food compartments as shown in thel drawin more in particular to refrigerator displaythe curved end member.

g. 3 is a etai] in'p rspective of the baille-- and r are disposed to. permit a sufficient airspace between them andthe upper` and lower sides of the case. The ice chamber is prov1de d with an apexed member 8 arranged to dlrectthe-air coming from the food com? partments 3 toward the cooling medium and provided at 'the bottom to directV the cool air and moisturetoward the bottom of the food chamber. Drains 10 are provided for egress ofthe water from the ice` In each food compartment there is provided a perforated baie plate 11 which ermitsV the warm air to pass through but o ers suflicient obstruction to cause the cooler air to fiow downward centrally in the-chamber. The baile plate is secured at the top of the chamber to a circularendplate'by means of screws or other fastening means and a space is provided between the ends of said late and the sides of the chamber. The en s 12 of the chambers 3 are given a large ,circular formation as shown and thebaiile plates 11 are placed adjacent the upper lends of said curved members where they join the ^top of the chamber. Suitable wire shelves 13 are provided .to support the food'. The. lower wire shelf 13 is positioned above the floor of the food compartment a suitable distance so as to afford a passage way or 'de-way for the current of cool air 'entering from the cooling4 chamber and to direct the same onto behind them and thus a greater amount of insulation is secured for ,said chamber. The general circulation of the air currents 1s shown by the arrows in the drawin from which it will be seen that the cool a1r from the lice chamber enters the food' chamber -at the bottom of the latter and com' into contact with the curved end is directe onto the baiile plate. On meeting this plate-the warm air, being lighter passes throu h the perforation in said plate while the co d air bein war The warm air a ain enters the cooling chamber at the top o 'the latter as shown.
